Different types of "Links"


Backlinks (or back-links (UK)) are incoming links to a website or web page. The number of backlinks is an indication of the popularity or importance of that website or page. In basic link terminology, a backlink is any link received by a web node (web page, directory, website, or top level domain) from another web node (Björneborn and Ingwersen, 2004). Backlinks are also known as incoming links, inbound links, inlinks, and inward links.

Obtaining backlinks from search engines

Most commercial search engines provide a mechanism to determine the number of backlinks they have recorded to a particular web page. For example, Google can be searched using (or to find the number of pages on the Web pointing to

Yahoo!’s Site Explorer is a method of obtaining the number of backlinks on a site.


When HTML was designed, there was no explicit mechanism in the design to keep track of backlinks in software, as this carried additional logistical and network overhead.

Some website software internally keeps track of backlinks. Examples of this include most wiki and CMS software.

Other mechanisms have been developed to track backlinks between disparate webpages controlled by organizations that aren't associated with each other. The most notable example of this is TrackBacks between blogs.

A Linkback is a method for Web authors to obtain notifications when other authors link to one of their documents. This enables authors to keep track of who is linking to, or referring to their articles. The three methods (Refback, Trackback, and Pingback) differ in how they accomplish this task.

Any of the four terms -- Linkback, Trackback, Pingback, or (rarely) Refback -- might also refer colloquially to items within a section upon the linked page that display the received notifications, usually along with a reciprocal link; Trackback is used most often for this purpose. Also, the word Trackback is often used colloquially to mean any kind of Linkback.

Linkback is also the name of an OLE-like open source framework for Mac OS X.

Refback Trackback Pingback
Trigger mechanism Visitor to linking site clicks on the link, and his browser takes him to the linked site Code on linking server examines added or updated documents, extracts links, and sends notification to linked server for each link found Code on linking server examines added or updated documents, extracts links, and sends notification to linked server for each link found
Notification medium HTTP referer value HTTP POST XML-RPC call
Capture mechanism Examination of incoming HTTP referer values Trackback capture script XML-RPC function
Information sent by linking server None
  • Linking site name
  • Linking post title
  • Linking post excerpt
  • Linking post URL
  • Linked post ID number
  • Linked post URL
  • Linking post URL
Additional information presented to linked server HTTP referer sent by a visitor's browser upon clicking the link IP address of linking server IP address of linking server
Autodiscovery mechanism (how the linking server finds out how and where to send the notification) None Specially-formatted information within the body of the linked page Special HTTP header or LINK tag on the linked page
Action required when notification is received
  • Extract referer value from incoming HTTP headers
  • Retrieve referring page
  • Parse retrieved page for desired information
  • Determine linked post from ID number
  • Retrieve page at "linking post URL"
  • Parse retrieved page for desired information
Advantages Requires no special code on linking server (the link itself becomes the notification when someone clicks on it) All the information desired by the linked server (Linking site name, post title, excerpt) is present in the notification itself
  • Notification mechanism has a complete technical specification
  • Less susceptible to spamming[citation needed]
  • No notification unless someone actually clicks on the link
  • Relies upon visitors' browsers sending proper HTTP referer information
  • Linked site must retrieve and parse linking site's page to extract the information it wants
  • Notification requires positive action by linking server
  • Extremely vulnerable to spamming (no requirement that the page described by the received notification actually exist)
  • Notification mechanism has only a partial technical specification
  • Autodiscovery information may prevent XHTML validation
  • Notification requires positive action by linking server
  • Linked site must retrieve and parse linking site's page to extract the information it wants
